  • 2x HDMI In & Loopout
  • Thumbwheel Switch Menu
  • Side OLED

Broader coverage, less latency

The 120m transmission distance supports a larger working range. The 0.1s ultra-low latency ensures instant transmission, allowing the cameraman to collaborate more efficiently with the director, lighting technician etc in the shooting or livestreaming team.

One-for-all thumbwheel switch

The function menu is operated by a thumbwheel switch.You can choose the desired function or channel by turning the thumbwheel switch. The thumbwheel switch is used to configure all settings, which effectively reduces the number of buttons on each device, making it more elegant and integrated.

Unstoppable power supply

The Mars 300 PRO can be charged via power bank(via USB-C port), DC adapter or NP-F battery and you can switch to a different power supply at any time. Multiple power supply options give you more power assurance.

Dual HDMI ports and loopout support

To allow you to connect more devices, both the receiver and transmitter provide two HDMI ports, which support simultaneous input and output. One of the HDMI ports on the transmitter is a loopout, which can output video to a small monitor on the camera and allow the cameraman to clearly see the shots.

All key info at a glance

The high-definition side OLED display clearly shows all necessary info including signal strength, remaining battery power and channel. Whether the device is installed vertically or horizontally, the screen will face you and you can see what is displayed without lowering the device.

Your phone is your monitor

You can monitor the shots with an app installed on your phone or tablet. The app provides additional functions including 3D LUTs, focus peaking, zebra and zooming. By turning phones into monitors, multiple team members can collaborate at zero cost.

Quick & Easy Firmware Upgrade via App

Once you have connected to the device using the mobile app, you can start the firmware upgrade by tapping a single button. It's so simple that even a newbie can easily complete the upgrade.
